I like Diva's examples.
Ed Murphy was a biometrics engineer working on the rocket-sled accelaration tests at (what later became) Edwards AFB in the late forties and early fifties. There is doubt among historians about what Murphy actually said; whether he was attempting to direct the finger of blame away from himself and onto a subordinate; or just sort of musing philosophically after a chimp had been run down the track with enormous trouble and at great expense, and no measurements were forthcoming because the meters were wired ground to plate. Murphy's offspring inclined toward the philosophical while his commanding officer suggested deflection.
Supposedly the first published formulation of Murphy's Law was "If it can go wrong, it will," but pretty much everyone agrees that Murphy said something different relating to the human propensity to screw up.
A more existential view might be phrased, "No matter how bad things look, you can always make them worse." I enjoy the broader and no-fault, "Innate Perversity of the Universe Theory" which subsumes Murphy's Law -- no matter how it's phrased.
Do you also wonder why, if we share 98% of our DNA with bonobo, they're so much smarter?
